The Spheres of Power books offer a whole range of alternative magic systems for Pathfinder and other d20-based RPGs. Problem is, there's only 20 books out there as part fo that series. Well, now, you can get them all together in one. The Ultimate Spheres of Power book puts them all in one place for you. This weighty tome is up on Kickstarter now.

From the campaign:

Spheres of Power was a new magic system released in 2014 and made for Pathfinder and other D20 systems. With its incredible flexibility and easy-to-use talent-based magic system, Spheres of Power quickly became a top-reviewed magic system and our top-selling product, and thanks to the generosity of patreon has been greatly expanded with the publication of over 20 handbooks of new and expanded content.

Now it's time to take all the lessons we learned, all the adjustments that have been made, and create the final, authoritative version of Spheres of Power, combining everything the system has become into a single, ultimate edition!

Ultimate Spheres of Power combines content from over 20 handbooks, including Spheres of Power, Expanded Options, Items of Power, The Temestarian's Handbook, The Telekinetic's Handbook, The Geomancer's Handbook, The Enhancer's Handbook, The Diviner's Handbook, The Abjurer's Handbook, The Auspician's Handbook, The Battlemage's Handbook, The Chronomancer's Handbook, The Conjurer's Handbook, The Creator's Handbook, The Destroyer's Handbook, The Illuminator's Handbook, The Mentalist's Handbook, The Necromancer's Handbook, The Nyctomancer's Handbook, The Shapeshifter's Handbook, The Trickster's Handbook, The Vivomancer's Handbook, and more into an updated, streamlined, and multi-faceted volume of amazing magic!
